I will say my main point again. Extreme breeding (as is done nowadays more than ever) has brought about many problems, both healthwise and temperament. Interbreeding cannot be good full stop. Using the same dogs time after time throughout pedigrees cannot be good. Concentrating purely on looks cannot be good. This type of planned breeding has caused nearly all these health defects in the first place!!
Good night, and Happy Christmas, Goldmali. May all your dogs be up to scratch in the show ring. LOL! I think you'll find if you went and got hold of some old copies of the dog papers (and F&F as that included cats then) , people said the same thing about "extreme breeding" a hundred years ago. :)
As JG said, INTERBREEDING is mating together UNrelated individuals of different breeds. INbreeding is mating together close relatives , and this CANNOT
cause any problems, it can ONLY bring to the fore what is already there. Therfore, it is SAFER to carefully line breed (more prefable to inbreeding) as you will not have any hidden surprises. If you always outcross then one day inevitably you will mate together two individuals that carrry the same fault. If you do some pedigree research in whatever breeds you're most interested in, you will actually find that dogs were inbred a LOT more 100+ years ago then they are now.
Showing is NOT actually "concentrating purely on looks". A show dog has to be of sound movement, which means it has to be correctly put together and function well which surely is essential for a pet, it has to be of good temperament, and of course it has to be in excellent conditon to do well. Its bite has to be correct . Hand on heart, does your bitch have such a good temperament that she would allow a total stranger to examine her at Crufts near to the main ring with the flyball going on with all the shouting without freaking out, total strangers throwing their arms around her neck without asking for permission first, and coping with all that such a show entails? Only dogs of good temperament can do it, and as such showing does help to promote good temperament.
Personally I firmly believe any good dog should be capable of doing it ALL .Whatever it's orignal purpose was AND look like its breed as well. And be healthy AND have a good temperament. That makes a good dog. The complete package, not one or the other. :)
Yes thank you, my dogs are actually doing very nicely in the show ring at the moment -except for the crossbreeds of course as they can only go to companion shows!

Won't be online tomorow now I'd guess as tomorrow is christmas and we'll be having our dinner and presents and then I'll be back when it is all over i.e. on Christmas Day. (Bet I'll be lonely here then ROFL.)
